KSTOCK LENGTHS OF STRUCTURAL SHAPESI nstead of the various stock lengths of Structurals being itemized herein, only the longest length carried in stock is shown Stock lengths of Bar Size Shapes, however, are listed herein .BAR SIZE AND STRUCTURAL SHAPESASTm Specification A 36A shape is classed a Bar Size Shape when its greatest dimension (length excluded) is less than 3 inches.

2 It is a Structural Shape when at least one of its dimensions (length excluded) is 3 inches or greater .The shapes listed in this SECTION conform to ASTM A 36, a standard specification for structural steel .ANALYSIS Carbon Phosphorus Sulphur .26 Max ..04 Max ..05 Max .APPLICATIONS For use in riveted, bolted, or welded construction of bridges and buildings, and for general structural purposes .mECHANICAL PROPERTIES ASTM A 36 requirements are: Tensile Yield % Elongation Strength Strength in (psi) (psi) 8 58,000/80,000 36,000 Min . 20% Min .a aSubject to a deduction from the above percentage of elongation for thicknesses under 5/16 and over 3/4 .wELDABILITY These shapes are easily welded by all the welding processes, and the resultant welds and joints are of extremely high quality.

3 The grade of welding rod to be used depends on thickness of SECTION , design, service requirements, etc .GALVANIZED SHAPESA ngles and other shapes listed herein can be furnished galvanized upon request .Sec. E Page 2 Sec. E Page 3 AISI STANDARD DESIGNATIONSS tructural ShapesListed on the following pages are shapes commonly carried in stock . The American Iron and Steel Institute has established a designation system for structural shape, which has been adopted by steel producers . In the column headed AISI Designation , a letter or letters precedes the size and weight per foot . For example, C3 x 4 .1 is the AISI designation for a 3 x 4 .1# Standard Structural ChannelShown below is a summary of the AISI designations: W shapes are doubly-symmetric wide flange shapes used as beams or col-umns whose inside flange surfaces are substantially parallel.

4 A shape having essentially the same nominal weight and dimensions as a W shape listed in the tabulation but whose inside flange surfaces are not parallel may also be considered a W shape having the same nomenclature as the tabulated shape, provided its average flange thickness is essentially the same shape as the flange thickness of the W shape . S shapes are doubly-symmetric shapes produced in accordance with dimensional standards adopted in 1896 by the Association of American Steel Manufacturers for American Standard beam shapes . The essential part of these standards is that the inside flange surfaces of American Standard beam shapes have approximately a 162/3% slope . M shapes are doubly-symmetric shapes that cannot be classified as W , S , or bearing pile shapes.

5 (Although not included in the standard nomenclature tabulation, bearing piles are doubly-symmetric wide flange shapes whose inside flange surfaces are essentially parallel and whose flange and web have essentially the same thickness .) C shapes are channels produced in accordance with dimensional standards adopted in 1896 by the Association of American Steel Manufacturers for American Standard channels . The essential part of these standards is that the inside flange surfaces of American Standard channels have approximately a 162/3% slope . MC shapes are channels that cannot be classified as C shapes .Sec. E Page 4 ANGLES BAR SIZESS tock Lengths 20 , 30 , & 40 as indicated Size Estimated weight, Lbs. In Inches Per 20-Ft. 30-Ft. 40-Ft.
